Abstract
Electromagnetic characteristics of metal polarization gratings are studied by means of the finite-difference time-domain technique in the case of long-wavelength diffraction of electromagnetic waves. Dimensions of gratings with rectangular bridges providing for optimal regimes of propagation of H- and E-polarized waves at the boundary between the microwave and terahertz ranges are determined. The influence of electric conductivity of metal elements on the transmission characteristics of the gratings is analyzed.
